APPLIANCE FOR SEALING PACKAGES.

Specification. of Letters Patent. Patented J 1y 21, 1 9514; Agolication filed November 24, 1913. Serial No. 802,823.

To all (whom it may concern Be it known that I, HENRI A. SIEVIGNI'J, a citizen of the United States, and resident of Winthrop, .in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Appliances for Sealing Wrapped Packages, .of which the following is aspecification.

This invention relates to the sealing .of wrapped packages and has reference particularly to mechanism or devices for fac litating the sealing of loaves of bread which have been wrapped in what is known as waxed paper.

While the appliance may be employed in connection with a machine for automatically and mechanically wrapping loaves of bread as descgibed and illustrated 111 my. application ,062 and may have means for applyin wax at the sealing point, yet, as explaine in my said applicat on, the means for supplying wax may be dispensed with and the pa er wrapper impregnated with wax or ot er' like sealin material adapted .to seal the several to ds of the wrapper when brought in contact with means for heatin .the same. My improved sealing a p iance however does not require that it s all be-used lnconnectlon with a machine which wraps the: articles,

,for the said articles, such as loaves of bread, may be wrappedby hand and then pushed through the sealing appliance, Wlth. the result that the portions of the package which require treatment are first heated, either for the purpose of meltin the wax carried by the paper or for app y ngwax in heated condition, and then cooling said portions of thepackage to retain the sealed portions in set position.

My invention consists in the mprovements which I" shall now proceed to describe and claim. r

Of the accompanying drawlngs: Flgure 1 is a plan'view, parts beln broken out in section, said view also s owing portions of a suitable framework for the appliance; Fig. 2 represents a longitudinabsection of the same, partly broken out or 1n section; Fig. 3 represents a section on line 33 of r Fig. 2.

Similar reference characters indicate similar parts in all of the views.

A suitable frame-work 2 supports the appliance, including a heated tank having a chamber 96 in its upper portion, the .chaniber 97 having-ta gas heaterpipe 97. Standards 104 support the table or cooling plate 105. A suitahlysupported pressure plate 120 may be employed to bear upon the upper surfaces of the wrapped articles B, such as loaves of bread to insure the "proper retention of the foldsof thewrapper at the under side in contact with the bottom of the uideway for the/articles. 4

T e parts s9 far. "described are indicated by the sani e rbfer'ence characters as the same parts illustrated anddescribed in my a.

nism included in the machine forming the subject matter of myapplication 602,062 -aforesaid, but not designated in the drawings thereof by nowbe explained.

Suitably supported are longitudinal bars 125, beyond the edges of the t szildfibars being a .sshall'be, held in proper position. TlllS is effected by mczfiis of the side plates 126 reference characters, will by the frame-work e "or coo 'fg plate hereinbefore described ilSv- Sllpf 1 cation 602,062. Other parts of the fite'c' aabove the side edges of the table 105 and of course adjustableto vary the space between the plates 126, this" being necessary to avoid damage to the articles 1n case some articles are longer than others. The plates have pins 127 projecting outwardly therefrom, springs 127 being inter-posed. between the plates 12 6 and bars 125, the outer ends of said pins passing through the bars 125 and screw-threaded and havln nuts 128 whereby the positions of'rthe p ates may be ad justed relatively to 'eachother, while at the the package which is passed between theiii will be compressed to a slight degree sufiicicnt to retain tlie 'folds in position. The nuts 128 enable the width of the opening or passa e'way between the side lates to be var'ie packages'that are bein passed between them.

wardly, as shown in Fig. 1, to' presenta flared entrance of the pa kage may n t bedamagedr same time permitting them to yield so th'dt The ends of the p ates l26 wherethe package enters are slightly turned outin order that the end folds Y r05 Y according to the leng of the 4 T he topof the tank 95, which I' have in dicated at 129, constitutes a heating table as hereinafter explained. A portion of this table carries wick material which, if kept saturated with wax such as paraliin, will be heated by the burner 97, the table surface 129 being of course also heated. To

hold the end folds of the wrapped package.

in proper position while the package is being passed Over the table 120, I provide side plates 12 ,0, which of course are yieldingly mounted and adjustable, as by means simis lar'toaneans for supporting the plates'126. 1n the drawings 1 also illustrate some similarly mounted side plates 131, these latter plates being employed when the appliance is used in connection with automatic folding mechanism such as described in my application ($03,062. if the sealing and'cooling appliance however upon? lmud-wrapped packages, then the plates 1:31 are not necessary.

lllieu articles such as loaves )f 'b1ead are wrapped somewhat in the manner indicated at B in the drawings,"are placed upon the heating tahle 129 and pushed in the'dired lion of-tlie arrow in lfig. 2, the wax carried byd-he wrapper will be melted and diffused so that when the package next passes along the guideway presented by the table 105' and Side plates 1%," the melted and diffused wa; will sot, thc paclrages' being'thereby sealed If "the paper that is employed is not-sullieient-ly heavily waxed to result in a. good seal being made, 'wax supplied to the w-ickiug' in the chamber 90 will be kept hot-Hand lllSlllilOlQIltlY melted condition to be "applied to the bottom of the packageas' it is pushed over it, the tablc'129 still fur- 'ther iliii'using the wax. Owing to the'spaceexisting between the table 129 and the table 105. and the similarspaces existing between the-plates 130 and theplates 120, the cooling portion oi the guideway is heat-insulated from the heating 'portion "of the guide'way.

I do not liuiit 'myselfhowever to providing a space as pist explained, since if the metal" of which. the guideway is const'ructed is of sutlicienily low conductivity, the heat from the burner 97 will not'be transmitted far enougl'i along the members 105 and 126 to interfere with-the cooling action or the farther portion. of the guideway, even if no. such space asijustldescribed exists. In 7 either case; the heating portion of the guide way ,oauses- .the Wrapper to assume and re-v j-,completcly '111010S1DQ-gth8 loaf.

A. as the articlesaremoved v alone, t and over the coohn )ortion of the -,iii 1uliiig the side plates 126, the

Owing, lo the fact that the bot-torn of v ta leau ooling plate 105- is flat, the sides is used for operation' pair has time tQSlZillClCnily cool so that 153?: living straight and at, a right angle the bottom, and there being an open space at the top as shown in the drawings, especially Fig. 3, it is entirely feasible to push the wrapped articles along from one end to the other of the guideway, either by directcontact of the hands or by means of pusher-s such as those illustrated at 34, in such manner that the bottom told as well as the end folds of the articles are held in "folded condition and kept smooth. 1 Moreover this may be done while the articles are still grasped by the hands of the user to avoid any possibility of the articles turning over or becoming twisted, or the folds becoming loosened. The pressure plate 120 is readily removable, as shown in my said application 602062,

as to leave the top opening entirely un-.

obstructed. Said plate, however, is of such width, as shown in Fig. 1, as to leave 'an open space each side of it for the movement or passage of the opcrators hands grasping a loaf and sliding it along over the bottom portions 129, 105, between the side plates. The frame and legs'of the machine'which are fully shown in my application 602062,

constitute supporting means'for all portions of the device, including the outer enjd'and the bottoms of the "portions referred to as tables. i

An appliance of the character described, comprising a straight guideway' having a fiat stationary bottom and straight sides at'a' right angle to the bottom, the appliance'having a top opening to permit articles to be pushed from one'end to the other, and means for heating one end or the guideway while permitting the other end to remain cool. 7
